Just an FYI for cold hardy stuff. Planted 30 started Cabbage and Cauliflower from Home Depot I bought early mid Feb. Planted them and onions on Mar 1st. On Mar 7 they saw 25 deg uncovered then I covered with a walmart sack and clothespins the following 5 days lows were 26, 22, 26, 22, 16 deg and they look like all made it.
